This invention relates to new useful improvements in ophthalinic. mountinlgs, and consists of a novel construction of temple, together' with means for sccuring the sanie to the lens rims ofa spectacle.

. The primary object of the presentinvention is to provide a hinga construction of the character stated, wherein the temples and the end pieces of the spectacle will have greater abutting surface with each other.

Another object of the invention is to provide a hinge connection which will be strong and durable in its construction and compact and neat in its appearance.

Another object is to provide an improved form of temple having a plurality of hinge ears, at least two of which are of different lengths.

Another object is to provide an end piece construct-ion which will retain its alignment and trueness of working parts during use.

Still another object is to provide a temple having a plurality of hinge ears, at least two of which ears contact with the end piece in different vertical planes.

`With thesey and other objects in view, the invention resides in the novel construction and combination of elements described in the following specification, illustrated in the accompanying drawings., and particularly in the appended claims.

In the drawings, wherein like characters of reference denote corresponding parts throughout the several views: i

Figure 1 is a front view of a pair of spectacles embodying the present invention;

' top plan view of *igure 2 is an enlarged the hinge connection;

Figure 3 is a Sectional view Figure 2;

Figure 4 is a top plan view of the templz,` per se; and

Figure 5 is a perspective View of the temple. 1

Vith reference to the accompanying drawing, in which is shownone practical embodiment of the present invention, designates a pair of lens rims of an. lordinary spectacle held together by means of a suitable bridge 11, and supported on the face of the wearer by the temple 12. Trlach of the lens rims 10 is split and separated end pieces 13 and 14, which are secured together by the screw 15.

on line 3-3 of of a portion the numer al i terminates in the serial no. 55,556;

It will he noted by reference to Figure 3 that azportion of the upper face of the end piece 14 is cut away to provide arece'ss, in wliichis received the 'smaller endpiecel 137 and that the said'end piece 14 extends bevond the end piece 13 and overlapsf the e nd face thereof, as indicated at 16;

Formed integrally with the end piece 14, is a locating lng 17, which is received within a recess in the end piece 13, which lug assists in retf'ining the said en'l piecesin alignment with each other. The e nd piece 14 is also provided with the spaeed vears 1.8 an'd`1-9, the recesses and 21, and the central slot V22. The temple 12 is formed with a head having the spaced hinge ears 23, 24 and 25, forming the resultant slots 26 and 27, the said ear 24 being somewhatilonger and wider than the ears 23 and. 25, as will be seen from the drawings. The'temple ears are arranged `to interengage with the ears 18 and 19 of the end piece 14, the slot 22 thereof extending into the end piece a greater distance than the rccesses 20 and 21vto accommodate the longer ear 24 of the temple.

By reference to Figure 2, it vwill be Seen that due to the fact that the hinge ear 24 of the temple is longer than the ears 23 and 225, the ear 24 will abut against the end piece on the line 28, while the shorter ears 23 and 25 will abut thereagainst at the point 29 when the temple is opened, or. in other words, brought to a position at right angles to the lens rim. I

'Vhen assembling the spectacle, the end pieces 13 and 14 are first brought together and the fastening screw 15' inserted therethrough, the lug 17 being received within the recess in the end piece 13. The hinge ears 23, 24 and 25 of the temple 12 are then interengaged with the ears 18 and 19 of the end piece 14, is inserted'through registering openings in the said end piece and temple ears, whereby to provideV a pivotal connection between the temple andend piece.

From f the foregoing readily appreciated that there has been provided a strong, sturdy, and neatly finished Jnd piece and it will, of course, be understood that various modifications in the specific details of the invention may be found and the right is hereby reserved to make any such changes as properly' fall within the after which a fastening screw 30' description it be I desirable, p

scope of the appended claims Wthoutdeparting from or Vexceeding the spirit of the invention. i

What isclaimedis:

1. In a device of the character described a lens rim endpiece having alternate perforated hinge ears and hinge ear recesses concentric about the center of the perforations with one of the recesses extended beyond'the concentric portion, a temple having alternate perforated hinge ears and hinge ear recesses concent-rio about the center of the perforations With one of the ears extended beyond'the con-` centric'portion and adapted to fit in the oxtended recess of the endpiece, the ears of the temple fitting'into the recesses of the endpiece and the extended ear of the temple into the extended recess of the endpiece with the perforations of the ears of the temple and endpiece axially aligned, and pivot means i throughthe aligned perforations,the said extended ear fitting into the extended recess inereasing` the rotative friction between the temple and endpiece to' prevent a loose or falling temple. t

2. In a device of the character described a a hinge member having alternate perforated hinge ears and hinge ear recesses concentric about the center of the perforations With one of the recesses extended beyond the concentric portion, a second hinge member having;` alternate perforatedv hinge ears and hinge ear recesses concentric about the center of the perforations with one of the ears extended beyond the Vconcentric port-ion and adapted to fit in the extended recess of the first hinge portion, the ears of the first hinge member iitting into the recesses of the second hinge portion with the extended earof one into the extended recess of the other With the perforations of the second hinge members axiallyV aligned, and pivot means through the aligned perforations, the extended ear in the extended recess increasing the rotative friction of the second hinge members.
